What are you asking? Any cable will work but usb3 will most likely the fastest your computer will accept. If you have apple, firewire is faster. Usb3.1 or usb-c would be even faster. If you really wanna nerd out, open up your PC case and direct connect to your motherboard with a sata cable, buy the necessary adapters for whatever external device you're using, and that device will most likely be your "bottleneck."
